Entry Lighting
The entry lighting system turns on the reading and
dome lamps and the backlighting to the exterior lamp
control when a door is opened or if you press the remote
keyless entry transmitter unlock button. If activated by
the transmitter, the lighting will remain active for about
25 seconds. The entry lighting system uses the light
sensor; it must be dark outside in order for the lamps to
turn on. The lamps turn off about 25 seconds after the
last door is closed. They will dim to off if the ignition is
on, or immediately deactivate if the power locks are
activated.
Parade Dimming
This feature prohibits dimming of the instrument panel
displays and backlighting during daylight hours when
the key is in the ignition and the headlamps are on.
This feature operates with the light sensor and is fully
automatic. When the light sensor reads darkness outside
and the parking lamps are active, the instrument panel
displays can be adjusted by turning the instrument panel
brightness knob. SeeInstrument Panel Brightness on
page 3-40for additional information.
Reading Lamps
The reading lamps are located on the overhead console.
These lamps come on automatically when any door is
opened.
For manual operation, press the button next to each
lamp to turn it on or off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.
Battery Load Management
The battery load management feature is designed to
monitor the vehicle’s electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle at a
higher revolutions per minute (rpm) setting than normal to
make sure the battery charges. High electrical loads may
occur when several of the following are on: headlamps,
high beams, fog lamps, rear window defogger, the
climate control fan at high speeds, heated seats and
engine cooling fans.
If the battery continues to discharge, even with the
engine idling at a higher rpm setting, some electrical
loads will automatically be reduced. When this occurs,
the rear window defogger may take slightly longer to clear
the glass and the fan may cut back to a lower speed.
For more battery saving information, see “Battery Saver
Active Message” underDIC Warnings and Messages on
page 3-79.

Electric Power Management
The vehicle has Electric Power Management (EPM) that
estimates the battery’s temperature and state of charge.
It then adjusts the voltage for best performance and
extended life of the battery.
When the battery’s state of charge is low, the voltage is
raised slightly to quickly bring the charge back up. When
the state of charge is high, the voltage is lowered slightly
to prevent overcharging. If the vehicle has a voltmeter
gage or a voltage display on the Driver Information
Center (DIC), you may see the voltage move up or
down. This is normal. If there is a problem, an alert
will be displayed.
The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles. This is
because the generator (alternator) may not be spinning
fast enough at idle to produce all the power that is
needed for very high electrical loads.
A high electrical load occurs when several of the
following are on: headlamps, high beams, fog lamps,
rear window defogger, climate control fan at high speed,
heated seats, engine cooling fans, trailer loads, and
loads plugged into accessory power outlets.EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s output
and the vehicle’s electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands
of some accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels of
corrective action, this action may be noticeable to the
driver. If so, a Driver Information Center (DIC) message
might be displayed, such as Battery Saver Active or
Service Battery Charging System. If this message is
displayed, it is recommended that the driver reduce the
electrical loads as much as possible. SeeDIC Warnings
and Messages on page 3-79.
Inadvertent Power Battery Saver
This feature is designed to protect the vehicle’s battery
against drainage from the interior lamps, trunk lamp,
glove box lamp, or the garage door opener. When the
ignition is turned off, the power to these features will
automatically turn off after 10 minutes (three minutes
if a new car has 15 miles (24 km) or less). Power will
be restored for an additional 10 minutes if any door
is opened, the trunk is opened or the courtesy lamp
switch is turned on.

E. Air ConditioningF. Heated Seat
G. Fan Control
H. Defrost
I. Rear Window Defogger
J. Air Delivery Mode
ControlAUTO (Automatic):The system automatically
controls the fan speed, air delivery, air conditioning
and recirculation modes in order to heat or cool the
vehicle to the desired temperature.
To place the system in automatic mode:
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting,
generally, between 70°F (21°C) and 80°F (27°C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool
any faster. If the system is set at the warmest
temperature setting, the system will try to
continuously heat the vehicle and will not adjust
the system down as the vehicle warms up.
To avoid blowing cold air in cold weather, the
system delays turning on the fan until warm air
is available. The system starts out blowing air
at the oor, but can automatically change modes
as the vehicle warms up to maintain the chosen
temperature setting. The length of time needed for
warm up depends on the outside temperature and
the length of time that has elapsed since the vehicle
was last driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature,
if necessary.
The display can be changed from English to metric units
through the Driver Information Center (DIC). SeeDIC

-(Defog):This mode clears the windows of fog
or moisture. Air is directed to the windshield and oor
outlets, with some air directed to the side windows and
outboard panel outlets. When this mode is selected,
the system turns off recirculation and runs the
air-conditioning compressor unless the outside
temperature is at or below freezing. If recirculation
is selected while in the defog mode, it is cancelled
after 10 minutes.
If there is fogging on the side windows, remain in defog or
defrost mode until they clear.
0(Defrost):This mode clears the windshield of fog
or frost more quickly. Air is directed to the windshield,
with some air directed to the side windows and outboard
panel outlets. The air-conditioning compressor runs
